Abstract (en)
[origin: EP3275406A1] A total knee implant prosthesis (10) is disclosed. The total knee implant prosthesis includes a tibial component (14) including a pair of bearing surfaces (54, 56) and a post (38) positioned between the bearing surfaces, and a femoral component (12) configured to rotate relative to the tibial component. The femoral component includes a pair of condyles (22, 24) sized and shaped to articulate on the bearing surfaces and a cam (36) positioned between the pair of condyles. The cam engages the post at a first contact point when the femoral component is at 0 degrees of flexion and engages the post at a second contact point located lateral of the first contact point when the femoral component is at a first degree of flexion greater than 0 degrees. The cam is disengaged from the post when the femoral component is at a second degree of flexion greater than the first degree of flexion.
